Patented Feb. 13, 1940 1 UNITED STATES @PATENT SMOKE PURIFIER Fon TOBACCO SMOKING ARTICLES Francis 11. ouuen, Philadelphia, Pa. Application August 29, 1936, Serial No. 98,542 .18 Claims; (01. 131-173) The invention relates to a smoke purifier for may be attached to 'a tobacco pipe, or may be used as a cigar or cigarette holder;

In the past, where Water has been used to' purify the smoke entering the smok ers mouth, 18 the practicehas been to use a purifier consisting of a tobacco bowl set upon an airtight Vessel partially filled with water, with a small tube connected to thetobaccobowl, which passes down into the Water and a long flexible smoking tube 90 or stem inserted in the side or top of the vessel above the water line. By exhausting the air in the top or the vessel thesinoke is forced down.

.through the water and upon entering into the space above it passes into the flexible tube. or 25 stem. This apparatus, besides being expensive; is cumbersome and generally may be used only for home purposes. Improvements of the .old style water pipe consists of complicated mechanism and traps to prevent leakage.

a An object of this invention is to provide a device, the functioning of which depends uponthe operation of physical laws relating to the behavior of a liquid in a continer, that is, liquid has a tendency to roll along the inner side of the a container when it is in a horizontal position'and twisted in the hands of an individual. Of course in utilizing the liquid in the container for sweetening, condensing, cooling and purifying the smoke from a tobacco bowl,.cigar or cigarette, provision is made that in the eventthe container is inverted or tilted, the inner tubes which direct the smoke in and out of the container have'openings properly spaced and sealed so that the liquid does not leak out.

;Therefore, the invention contemplates a tobacco smoke purifier which comprises a body made of wood, glass; laminated substances or other suitable material, which body contains a condensing chamber and a discharge chamber 50 with tubes in the center for directing the smoke,

all of which are connected by a restricted passage, the parts so formed that the passage is normally closed to the smoke by a liquid seal. When held in the mouth of a smoker, the induction tube from the tobacco chamber, instead of extending into the water, as in the old style water pipe, sets above the liquid, the successful operation depending upon'the volume oflliquid held by the purifier (the volume can be determined by a measuring device which forms a part 5 of the purifier) and the air space in the discharge chamber being sufficient so that the liquid is not sucked into the smokers mouth, the

, openings in the tubes sufficiently spaced, and the ends of the'tubes nearest the openings sealed, so that regardless of the position of the liquid held in the purifier it will not leak back to wet the tobacco or enter the smokers mouth. I The shape may be as in Fig. 1, that is, the purifier is curved in order that it may hold a tobacco bowl (which 5 maybe fastened, screwed or plugged in with a cork holder or other material to prevent leakage) or it may be horizontal as shown in Figs. 2 and 3 for insertion into a tobacco pipe or for holding a cigar; or cigarette. As maybe observed from Fig. 1, thesmoke passes down through the liquid sealand it also does likewise in Figs. 2 and 3 because the draft created bythe smoker causes the smoke to reverse itself so that it passesdown through the liquid seal and out into the discharge 2 5 the condensing chamber would have a "tendency to sweeten and cool the tobacco bowl. In

the case of Figs. 2 and 3, at'no time would all of the liquid rest in either the condensing chambers, the same as in Fig. 1. As for the small 40 quantity of liquid held in the condensing chamber, the liquid would roll when the purifier is twisted and if the purifier is tilted or inverted,

proper spacing of the openings and seal 'would prevent the liquid from leaking out.

Another object of the invention is the'provision of a tobaccosmoke purifier which is light in weight sothat when attached to a tobacco pipe it does not materially increase its total weight.

Another object of the invention is the provision of a tobacco smoke purifier which is small in'size so that when attached to a tobacco pipe it does not materially increase its size. Another object of the invention is the provision of a tobacco smoke purifier in which the pasis the provision of a measuring device that is attached and which forms a part of the tobacco smoke purifier, its function being to indicate the Volume of water or other liquid that is to be held by the tobacco smoke purifier.

Also another very important object of the present invention is the visibility of a tobacco smoke purifier (which may be made of glass or trans parent laminated plastic material) so that the smoker may see the operation of the device and from the discoloration of the liquid know when to change the liquid in the purifier.

The device and method have been employed with success using water and other liquids and the invention therefore is described with particular reference to this use.

The liquid sealed restricted opening illustrated in Fig. 1 can be formed by the use of a tube but this is not so desirable because the purifier would be unnecessarily increased in size due to the length of the tube and the air space required in the discharge chamber.

With the above and other objects in View, this invention consists of the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same I will describe its construction in detail, referring by numerals to the accompanying drawing, forming a part of this specification, in which:

Fig. l is a longitudinal sectional view of a tobacco pipe illustrating one construction utilizing the principles of my invention.

Fig. 2 is also a longitudinal sectional view of a pipe stem which may be connnected to a pipe bowl and constructed according to this invention but slightly modified from Fig. l.

Fig. 3 is a longitudinal section of the body or stem structure showing a socket for use as a cigar or cigarette holder.

Fig. 4 is a similar view of the mouth piece. and component parts.

Fig. 5 is a section on the line 5-5 of Fig. 1, looking in the direction of the arrows.

In carrying out my invention as herein embodied, reference being first had to Figs. 1 and 5, the numeral ill represents an outer or pipe bowl having a stern body II with a large bore communicating with the interior of the pipe bowl it through a restricted opening or hole I2. This opening or hole can be formed by a tube. A mouth piece !3 is removably mounted in the outer end of the stem body 5 I and has a bore Ml therethrough for the passage of smoke as is usual The mouth piece l3 carries a tube l5 projecting from its inner end, which tube extends a suitable distance into the large bore of the stem body and occupies approximately the longitudinal center thereof. This tube I5 is of less length than the stern body and has a larger tube or cylinder l6 on its inner end, said cylinder I6 preferably engaging an end wall to close the open end of the cylinder when the apparatus is assembled. The tube 15 andthe cylinder It forms a discharge chamber ll between them and the walls of the stem body ll, which chamber communicates with the interior of the pipe bowl W through the opening l2 and with the passageway in the tube it through an orifice l3 intermediate the endsof' said tube and the inner end of said tube is closed. The closure may be produced in any suitable way but, forpurposes of illustration such closure-is shown as a plug 19 inserted in the tube beyond the orifice E8.

The tube l5 and cylinder 56 may be produced in any desirable way,'that is, they may be made from a single piece ofmaterial or former separately and joined together. They may be assembrings the tube l5 into communication with the bore I4 of said mouth piece.

A quantity of Water or other liquid 25) is placed in the chamber H and occupies some of the bled on ,themouth piece 53 in any manner that I space or condensing chamber within the lower.

part of the pipe-bowl It to seal the opening H.

To preventthe tobacco from coming incontact with the liquid seal 20, an inner or tobacco bowl 2| is mounted inside of the pipe bowl H), and said tobacco bowl 2! is smaller than the pipe bown to provide a space 22 surrounding the tobacco bowl 2|. Said tobacco bowl has an induction tube 23 into which a hole 2 1 entersfrom the bottom of the tobacco receiving chamber in the bowl 2| with lateral openings 25 forming com munications between the hole 24 and the exterior of the induction tube 23 or the interior of the pipe bowl l0. I

The cylinder H5 is used as a measure to gauge the amount of liquid at v fier and whena quantity of the liquid equal to the capacity of said cylinder is inthe purifier, the opening I2 is liquid sealed at such times as the pipe is held in a substantially horizontal position or in an inclined position as'illu'str'ated. As the user induces a draft through the pipe the to be placed in the purismoke will follow the directions of the arrows and I flow from the tobacco bowl 2| through the hole 24 and openings 25 into the pipe bowl lb, thence through the restricted opening l2 and itsliquid seal, the chamber ll, orifices G8, the tube i5 and the bore of the mouth piece l3. During the pas-' sage of the smoke through the liquid seal said smoke will be purified, cooled and sweetened thus producing a satisfying flavor.

Because of the provision of the induction tube 23 and the openings 25 an inconsequential amount or none of the liquid sealing agent will enter the tobaccov bowl when the pipe is shaken or even inverted and when tilted or inverted the liquidwill occupy the space 22 or the chamber I! or both and will not spill out and so the pipe can be carried in a pocket or pouch without fear of losing the liquid or soiling the clothes. Any of the liquid in the chamber ill will rollalong the inner surfaces of the chamber walls and is un- I likely to enter the tube l 5 butbecause the orifices I8 are directly opposite each other should some of the liquid pass into one orifice it generally.

will pass right through the other orifice:

The modification illustrated in Figs. 2, 3 and 4 includes a stem body 25 with anapertured connector 2'! at one end and a mouth piece28 at the other end, the latter preferably being removably attached to the stern body and has a bore 29 running longitudinally therethrough. connector 21 may be separate from the stem body 26, as shown, or obviously it may be anintegral part thereof and it may be in the form of a plug,

' An induction tube 3| is carried by theinne'r end of the connector and is located wholly within the stem body occupying the longitudinal center thereof. Surroundingthe intermediate por'-'- from the same piece of material, as shown, or

Said induction tube 3| has oppositely end of the cylinder and preferably outside of the cylinder 32 so that access maybe readily had to them for cleaning purposes.

A tube is carried by' and projects from the inner end of the mouth piece 28 and the interior of said tube communicates with the bore ofsaid mouth piece." closed in any communications between, the interior and exterior of said tube. A cylinder 38 is carried by the inner end of the tube 35 an'dis closed at its outer end where it joins with the tube and open at its inner end. scope, one 'over the other, and for purposes of illustration, the cylinder 38 is shown large enough to fit over the cylinder '32.. When the parts areassembled the outer end of the ind uction tube3l will be closed as'well as the inner endof the tube 35 andthe combining of the two cylinders will produceaninner chamber 39 and A quantity of liquid which will re'ach to an approximate level 4| when the appliance istheld in an inclined position, as shown in Fig. 2, is}

placed in the outer chamber and forms a liquid seal forthe restricted opening 33. The parts-of the apparatus should be so proportioned and the quantity of liquid should be such that said restricted opening 33 will be sealed by the liquidsealing agent even though the'device is held in-an approximately horizontal position.

Due to the staggered relationof, the orifices-34 and 31 and the restricted opening 33 relative to each other the sealing'liquid'is unlikely to pass into the tubes and therefore willbe retained re} gardless of the position of thebapplianoe when not in use.

While employed for smoking purposes a draft will be induced through the appliance and :to-

j bacco smoke will flow through the apertured con I condensed, cooled and nector 27, induction tube 3|, orifices34, chamber 39, restricted opening 33, chamber 40, orificesii'i.

tube 35 and the bore 29 of the mouth piece. As the smoke travels this circuitous route'it will passthrough the liquid seal and be sweetened, purified before reaching the smokers mouth.

The Walls of the chambers holding the liquid; seal can be ofglass or laminated material so that the'operations will be visible. Theparts can, be

readilyand easily disassembled for cleaning purposes and when the mouth piece with its componentelementsare disconnected from the stem body, the cylinder 38; can be used'to mea'sure the quantity of water or other liquid sealing agent to be placed in the chamber 49.

Of course I do not wish to be'limited to the exact details. of construction herein shown and described as these may be varied within 'the' 2,190,312 Fig. 2, for insertion in a pipe bowl 30- or rash- The inner end of the tube 35 is suitable manner, as-by a plug 36 I but has oppositelydisposed orifices 31 to'provi'de Thecylinders '32 and 38 telescope ofthe appended claim without departing from thetspirit of my invention.
